A cantilever beam AB of length L=12 m is subjected to a concentrated load P = 35 kN anda couple M0= 15 kN-m acting at the free end (see figure). Using Moment Area Theorems,obtain the angle of rotation θB and the deflection δB at end B. Young’s Modulus E = 200 GPa and the Moment of Inertia I=105x10^6 mm^4

Two vertical forces are applied to a simply supported beam with the cross-section shown: If L1 = 1 m, L2 = 3 m, and P = 10 kN, determine the maximum tension bending stress in the beam. The beam's moment of inertia about the z axis is 10,577,574 mm^4 and the centroid of the section is located 139.1 mm above the bottom surface of the beam.
